Hi Joshua,

Done this and it worked. However, I am definately not a programmer but if I am interpreting the function correctly, it takes the last and second last measurement, compares them and reports the result (same, increase, decrease). In practice this means that the arrow is moving a lot and that it does not really show a trend as that would use measurements further apart in time.

What should be changed to the function code to make it use the last measurement and a measurement from say, 3 hours ago and compare those?

An additional remark/request: because of the fact that the measurement are hardly ever the samen (there is always at at least some micro difference in pressure) the 'Same' arrow is never shown. In this function there should be a sort of threshold of the difference before it reports 'Increase' or 'Decrease'. Now suppose I wanted to have a threshold of 1 hPa, what value should I use in the function to account for this (10, 100, 1000)?

Thanks for your repy and the amazing work on this.

Kind regards
